SAVING CHANGES TO LINKED-IN PROFILE
I just discovered this for myself and thought the resolution might be worth spreading, given the number of folk raising the issue in the Help Forum.
I was trying to change my profile this morning, but found that I couldn’t save the changes. Tried again, no difference; logged out and in – that save button was still unresponsive! Much grinding of teeth and cursing! Thankfully I work from home so only the dog was offended!
Went to the Help forum and was reminded that clearing my cache might work. And it did! Your cache is your browser history and cookies etc. Very easy to fix – just go to history and hit the button that clears from the beginning of time. And you are good to go. Worked for me, just now. Let me know if it works for you.
